Mode opératoire

To a mixture of 4-bromo-2-nitroaniline (217 mg, 1.0 mmol), phenylboronic acid (122 mg, 1.0 mmol), tetrakis-(triphenylphosphine)palladium (55 mg, 0.05 mmol) and cesium carbonate (650 mg, 2.0 mmol) was added 3 mL of ethyleneglycol dimethyl ether (DME). The reaction was heated to 80° C. and stirred under nitrogen atmosphere overnight. The mixture was filtered through a celite pad. The filtrate was concentrated and purified by biotage column chromatography to give 4-nitrobiphenyl-3-amine (207 mg)
